Не устанавливается wb-scada-client

Добрый день. Помогите разобраться. После прошивки SCADA Client и WebUI Configuration schema исчезли. При установке wb-scada-client выводится сообщение:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
b-scada-client : Depends: python-mqttrpc but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Установка python-mqttrpc вызывает ошибку:

The following packages have unmet dependencies:
python-mqttrpc : Depends: python:any (< 2.8) but it is not installable
Depends: python:any (>= 2.7.5-5~) but it is not installable
